What is the purpose of the "air blast" technique in aerial application?

The air blast technique in aerial application is primarily utilized to enhance the penetration of spray into crops. This method involves directing a powerful stream of air along with the pesticide to ensure that the spray efficiently reaches the foliage and is effectively deposited where it is needed. By using this technique, the distribution of the chemical can be optimized, allowing it to penetrate dense canopies or reach plants more effectively when dealing with taller crops or those with thicker foliage.

Penetration is crucial in ensuring that the treatment is effective, as it allows for better absorption of the pesticide by the plant, which can lead to improved control of pests or diseases. This method takes advantage of the aerodynamics and dynamics of airflow to achieve a targeted application, promoting better results from the aerial application process.

While minimizing pesticide usage and reducing chemical drift are important aspects of aerial application, the primary focus of the air blast technique is on improving spray penetration to ensure that the desired area is effectively treated. Improving flight stability, while beneficial for overall safety and accuracy in application, is not the main goal of this technique.
